WILLIAM A. HALL, OF LOS ANGELES, CALIFORNIA.

FOLDING KNIFE.

To all whom it may concern:

Be it known that I, WILLIAM A. HALL, acitizen of the United States, residing at Los Angeles, in the county of 'Los Angeles and State of California, have invented a new and useful Folding Knife, of which the following is a specification.

This invention relates to a folding knife, and the object of the invention is to provide a complete housing for the blade of the knife when folded and to securely close the said housing preventing the knife from accidentally opening.

A further important object is to provide means for securely holding the blade locked open when in open position.

A further object is to provide a construction wherein there are but three parts aside from the blade, all of which parts may be quickly and economically constructed of sheet metal.

A further object is to dispense with rivets, screws and the like and to construct all pivot features as integral with the associated parts.

Referring to the drawings:Figure 1 is a perspective view of the several parts of the knife before assembling. Fig. 2 is a perspective view of the knife as closed. Fig. 3 is a perspective view of the knife open ready for use. Fig. 41 is a perspective View of a modified form of knife as closed. Fig.

5 is a plan view of the form shown in Fig. 4, as open ready for use. Fig. 6 is a side elevation of the knife closed.

The knife comprises a box shaped casing comprising a body portion 1 and a cover 2, which parts form the handle of the knife. The body portion 1 is constructed of a single piece of sheet metal, the sides 3 being bent up at right angles to the bottom 4, and the end formed of a tongue 5 which is bent up and over, as shown in Fig. 2. The end of the tongue 5 is slotted to form a pintle 6, and the cover 2 has a tongue 7 which is bent loosely around the pintle 6, dotted lines in Fig. 1 representing the manner in which the tongue 7 is bent around. This construction hinges the cover 2 to the box portion 1. The side members 3 have two perforations 8 which are in line with each other when the sides are bent up, and the shank 9 of the blade 10 has trunnions 11 formed thereon which are journaled in the perforations 8. The shank 9 is also slightly wedge-shaped, as shown in Fig. 1, so that when the cover 2 Specification of Letters Patent.

is in place the slide 12 forces the cover tightly into engagement with the shank 9, the wedge-shape of the shank 9 acting to wedge the blade securely between the cover and the box as the slide 12 is moved out ward, thereby preventing any looseness of the blade and also acting as a stop to prevent the slide 12 from being pushed completely off the end of the box. The slide 12 is bent up from a single piece of metal, as indicated in Fig 1. hen the knife is folded, as shown in Fig. 2, the point of the blade lies toward the rear end of the box 1 and the blade lies within the box under the cover 2, and the slide 12 is pushed to the outer end to hold the cover 2 in place, thereby securely retaining the blade within the box. To open the knife the slide 12 is moved to the opposite end of the box which permits the cover to be swung open and then the blade may be opened out after which the cover is returned and then the slide is moved out to force the cover against the wedgeshaped shank 9.

In Figs. 4: and 5 I have shown two extensions 13 pivoted to the slide 12, which extensions may be folded in against the box, as shown in Fig. 4:, or may be extended out, as shown in Fig. 5. The extensions 13 act as guards to prevent the hand from slipping down on the handle of the knife. This form is particularly adapted as a hunting knife, it being very strong and rigid when extended and folding into very compact form when closed, and when the knife is closed there is no danger in carrying the knife as is the case with hunting knives of the ordinary type.

lVhat I claim is 1. A knife comprising a box, a blade pivoted at one end of the box, a cover pivoted at the other end of the box to swing in the same plane that the blade swings in, and a slide movable along the box to hold the cover against the blade with the blade either open or closed.

2. A knife comprising a handle formed of a box member, a cover for the box, one end of said cover being pivoted to one end of said box, a blade having a wedge-shaped shank pivoted at the other end of the box, and a slide movable along the box to clamp the wedge shaped shank between the adjacent ends of the box and cover.

3. A knife comprising a box and a cover,

the box being formed of a single piece of metal, the sides of which are bent up and the rear end of which is bent up and over, the end piece being slotted to form an integral pintle, said cover being formed of a single piece of sheet metal, the end of which is curled around the said pintle, a blade having trunnions pivoted in the sides of one end of the box, and a slide movable along the box to clamp the cover against the blade when open or shut.

4. A knife comprising a box and a cover, the box being formed of a single piece of metal, the sides of which are bent up and the rear end of which is bent up and over, the end piece being slotted to form an integral pintle, said cover being formed of a single piece of sheet metal, the end of which is curled around the said pintle, a blade having trunnions pivoted in the sides of one end of the box, and a slide movable along the box to clamp the cover against the blade when open or shut, the shank of the blade being wedge-shaped.

5. A knife comprising an elongated box, a cover for said box, said box being closed on the top for a short distance, a slide on the box, the width of which slide does not exceed the length of said closed portion, a cover having one end pivoted to said closed portion, and a blade pivoted at the other end of the box to swing in the same plane with the cover.

6. A knife comprising an elongated box,

a cover for said box, said box being closed 011 the top for a short distance, a slide on the box, the width of which slide does not exceed the length of said closed portion, a cover having one end pivoted to said closed portion, a blade pivoted at the other end of the box to swing in the same plane with the cover, and extensions pivoted to said slide and adapted to be folded against the box or extended at right angles thereto.

7. A knife comprising a box, a blade pivoted at one end of the box, a cover pivoted at the other end of the box to swing in the same plane that the blade swings in, a slide movable along the box to hold the cover against the blade with the blade either open or closed, and a pair of extensions pivoted to the slide, each extension comprising a single piece of sheet metal bent to form wings adapted to fold over the box portion.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 10th day of'March, 1909.
